Primaluna?

Primaluna has 'adaptive autobias'. So not at all the same thing. So many people here like to say autobias has been around forever. But it's not the same animal.

Try putting a kt150 next to an el34 and every other kind of tube in between. Can't do that with other designs. Look at the autobias boards in a Primaluna...not the same animal.

Every design is a compromise...Primaluna gets you close enough to the best but makes concessions to reliability. It's one of the reasons I went with this brand. After a bad experience with a Don Sachs Kootenay, I decided that I didn't need the drama. The Kootenay sounded a little better when it worked. 

In my room I've only had BAT but wonder about how it'd compare to PL, ARC, and especially Rogue.  Yes replace all the tubes at the same time, else your mind will devour itself when you start hearing things that don't quite sound right.  Best feature not explicitly mentioned above is 3 sets of taps to match diff't speaker impedances.  

When I decided I wanted to get my feet wet with a tube integrated I was looking for the best bang for my buck. I went with a Jolida Fusion 6802 on close out from Walter. I like it a lot but that’s coming from a guy that had only had receivers in the past running a pair of Canton Karat 930 bookshelf speakers from ‘93.
Without question tubes are for me. Within the 2 years I’ve had the Jolida, I’ve gotten a hold of a set of PSB Imagine T speakers(not the best but better than the Cantons), MHDT Orchid DAC (For CD Transport) and still waiting for my Decware phono stage. After I receive the Phono Stage, a much better pair of speakers will be next. I then will evaluate where I go with the amp.

I guess what I’m saying is it’s been a learning experience and may be one for you. So don’t hesitate to buy a Prima Luna and enjoy the journey.

+1 for Primaluna.

I started with a used Prologue One and later upgraded to a new Prologue Premium. I have been very pleased with my Primaluna amps. In addition to driving my Harbeths, they also handle my hard to drive Maggie 1.7i’s without breaking a sweat. I also have a Hegel Rost integrated, which I greatly enjoy, but I I keep coming back to the Primaluna as my preference. You won’t go wrong with a Primaluna, and you’ll certainly thank yourself for stepping into the magical sound of tube amplification. (I always buy a new quad of tubes when it’s time to replace.)
